REGISTER AND VENTILATOR CONSTRUCTION.

Specification of Letters Patent.

Patented Dec. 2, 1913.

To all whom it may concern:

Be it known that I, EDWARD (J. Goonwrn, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Register and Ventilater Construction, of which the following is a full, clear, and exact description.

This invention relates to registers, ventilators, and similar devices and is more particularly concerned with means whereby the register or ventilator frame may be readily and quickly attached to, and detached from the outlet or inlet end of an air-conducting pipe and the like.

The invention is designed to provide a very simple device of this character adapted to air pipes and register frames of standard construction without any material modification of their structure, as will be fully described in the following specification taken in connection with the accompanying drawings forming part thereof and illustrating a preferable embodiment of my invention.

In these drawings Figure 1 is a front view of the frame of a hot air register or ventilator attached to an air-conducting pipe by the means forming the subject matter of the present invention. Fig. 2 is a horizontal sectional view on the line 2-2 of Fig. 1. Fig. 3 is a fragmentary horizontal sectional view through the register frame and pipe casing, showing the register frame applied to the air-conducting pipe with the clamping means in operative position. Fig. i is a similar view showing the clamping means actuated to clamping engagement with the pipe. Fig. 5 is a fragmentary vertical section on the line 55 of Fig. 3. Fig. Gis a detailed view in top plan and end elevation of the angle bar clamping member. Fig. 7 is a detail view in top plan and front elevation of the leaf spring employed in conjunction therewith.

Referring to the drawings by numerals, 1 indicates the walls of an upright air-conducting pipe which is provided with a later ally extending aperture 3 therein and with outwardly extending flanges 2 extending about the aperture 3 in said pipe.

t indicates the frame of a hot air register or ventilator provided on its front face with a grille or grating 5 shown as, and preferably integral with the frame l. This register or ventilator frame is adapted to be secured to the flanges 2 extending about the opening in the air-conducting pipe, and to cover said. opening, the grating of said register being positioned in front of said openmg.

It is desirable that means be provided whereby the register frame may be quickly positioned over the flanged opening of the air pipe and be securely clamped thereto; also that said clamping means may be such that the register frame may be quickly and easily detached from the pipe. To this end I provide on the inner face of the register frame, a plurality of angle bars forming clamping members, these angle bars being preferably shaped to provide an acute angle and each having a base 6 and a clamping flange 7, and being provided atsuitable intervals with threaded bores S therein. These angle bars are movably secured to the reg ister frame by means of screws 10 extending through suitable apertures in said frame positioned to register with the threaded bores in the angle bars. They are, further more, arranged to conform substantially to the interior contour of the flanged pipe opening. In order that they may be positioned for ready insertion within the flanged opening of the pipe, leaf sprin 9 are preferably employed, these leaf springs being apertured to fit over the screws 1.0 and rest against the inner face of the register frame and against the under face of the base 6 of the angle bars. These angle bars, forming as they do an acute angle, must be thrown inwardly so that their clamping flanges 7 will be perpendicular to the register frame or inclined slightly beyond. This is necessary, in order that these flanges, when the register plate is applied to the flanged opening in the pipe, may extend within said opening and lie adjacent the flanges 2 of said pipe, the leaf springs i) normally tending to throw these clamping flanges 7 to or beyond the perpendimllar. The screws 10 extend freely through suitable bores formed through the register frame and engage with the threaded bores S of the clamping angle bars. It will be obvious, therefore, that when the register frame has been applied to the flanged opening in the air pipe 1 with the clamping flanges 7 of its angle bars thrown inwardly to or beyond the perpendicular, that these screws 10 may be turned to draw the base portions 6 of the angle bars downwardly against the pressure of the leaf springs 9, thereby throwing the clamping flanges 7 of the angle bars outwardly against the inner faces of the pipe flanges 2, to move and hold said flanges in clamping engagement with the pipe flanges 2 and thereby support the register frame therefrom. It will be evident that in order to remove the register frame from engagement with the pipe it is only necessary to operate the screws 10 in a reverse direction whereupon the pressure of the leaf springs 9 will throw the clamping flanges 7 of the angle bars inwardly and away from the clamping engagement with the pipe flanges 2, whereupon the register frame may be readily removed from the pipe without damage thereto.

Where the openin in the air-conducting pipe is square or rectangular in crosssection, as shown in the drawings, I may employ three removable angle bar clamping members as described, these being located at the sides and top of the frame and may place at the base of the frame a right angle bar 11 (see Fig. 5) rigidly secured thereto as by rivets 12 and positioned to fit within the opening in the air pipe and rest on the inner face of the bottom flange 2 thereof. It will also be obvious that the contour of the clamping angle bars may vary with the cross section of the opening in the air-conducting pipe and with the shape of the register frame cooperating therewith.

While I have shown and described herein a preferable embodiment of my invention, I desire it understood that various structural changes therein are possible within the spirit of the invention and the scope of the appended claims.

What I claim therefore, and desire to secure by Letters Patent is:

1. In a device of the character described, an air conducting pipe having an opening therein with a projecting flange at the border of said opening, a register frame arranged to cover said opening and flange having a perforated portion located in front of said opening and having within its edges and within the internal area of said flanged opening a supporting flange carried and fulcruming at the back of said frame to swing relatively-thereto, and in one direction of movement to frictionally engage the inner face of said projecting pipe flange, and manually operable means for swinging and holding said frame flange, in frictional engagement with the inner face of said pipe flange to thereby support said frame upon said pipe flange.

2. In a device of the character described, an air conducting pipe having an opening therein with a projecting flange at the border of said opening, a register frame arranged to cover said opening and flange having a perforated portion located in front of said opening and having within its edges and within the internal area of said flanged opening a supporting flange carrying and fulcruming at the back of said frame to swing relatively thereto, and in one direction of movement to frictionally engage the inner face of said projecting pipe flange, and manually operable means for swinging and holding said frame flange in frictional engagement with the inner face of said pipe flange to thereby support said frame upon said pipe flange, said manually operable means being positioned and arranged for access from the front of the frame.

3. In a device of the character described, in combination, an air-conducting pipe having an opening therein and having a flange projecting outwardly therefrom, a frame adapted to be positioned in front of said opening, an angle bar carried by the inner face of said frame and provided with a clamping flange, spring means cooperating with said bar to position its flange within said pipe opening when said frame is applied thereto, and screw means cooperating with said frame and angle bar to move said clamping flange into clamping engagement with said pipe flange to thereby support said frame therefrom.

4. In a device of the character described, in combination, an air-conducting pipe having an opening therein and having a flange projecting outwardly therefrom, a frame adapted to be positioned in front of said opening, an angle bar forming an acute angle mounted on the inner face of said frame and having a threaded bore therein, a screw carried by said frame and cooperating with the threaded bore of said angle bar, and a spring between said frame and angle bar normally tending to position one of the flanges thereof within said pipe opening when said frame is applied thereto, said screw being adapted to be operated to move said bar flange against the pressure of said spring and into clamping engagement with said pipe flange to thereby support said frame thereon.

5. In a device of the character described, a register frame having a portion of its face perforated for the passage of air, and having a flanged portion extending inwardly and rearwardly from the inner face of said frame at the edges of said perforated portion, part of said flanged portion being eX- pansible laterally relative to the frame, and manually operable means for expanding said part and for holding it in expanded position.
